Abstract

The purpose of this study is to figure out the characteristics of teacher's scaffolding that can promote the social construction of scientific models by analyzing a teacher's scaffolding that actually promoted the social construction in a real classroom context, so that we can better understand the teacher's scaffolding. For this study, a total of 32 middle school students and their science teacher in Seoul were observed and videotaped. The level of social construction were categorized in four stages. We divided the teacher's scaffolding by whether the level of social construction has changed or not, and analyzed teacher's scaffolding in each group. Teacher's scaffolding were categorized based on its object, purpose and means. The object were categorized into two types; small-group and individual. The purpose were categorized into two types; process-help and product-help. The means were coded into Diagnostic strategies(Reading, Listening, Questioning), Checking diagnosis and Intervention strategy(Instruct, Explain, Hint, Confirm). The result show that teacher's scaffolding is helpful in the social construction of scientific models when it supports small-groups more than individuals, and process-help more than product-help. It also shows that in diagnostic strategies, questioning and listening are effective. Finally, using checking diagnosis promoted interactions among students and a 'confirm' intervention strategy should be avoided because it has no positive effect on changes in the level of social construction. This study provides the features of the teacher's scaffolding that promotes social construction of scientific models in middle school classes.

본 연구에서는 중학교 과학적 모형의 사회적 구성 수업에서 사회적 구성을 촉진하는 교사 스캐폴딩의 특징을 알아보기 위해 중학교 2학년 8개 소집단에게 소리의 발생과 전달을 주제로 수업을 진행하여 3차시 동안 모형의 사회적 구성 수준과 수준의 변화를 탐색하고, 사회적 구성을 촉진하는 교사 스캐폴딩을 대상, 목적, 방법으로 분석하여 사회적 구성을 촉진하는 교사 스캐폴딩의 특징을 살펴보았다. 사회적 구성을 촉진하기 위한 교사 스캐폴딩은 첫째, 개인의 인지 발달보다 소집단을 대상으로 스캐폴딩을 지원하고 있었다. 둘째, 결과적 도움보다 과정적 도움을 지속적으로 제공해 주어 참여와 토론을 강조하고 있었다. 셋째, 학생들의 요구와 수준에 맞는 전략을 제공하기 위하여 진단 전략과 진단 점검을 사용하여 학생들의 이해 정도와 상황을 파악하고 학생들에게 적합한 전략을 제공하고 있었다. 이러한 결과를 토대로 과학적 모형의 사회적 구성을 촉진하기 위해 교사가 스캐폴딩을 어떻게 지원해야하는지에 대한 시사점을 얻을 수 있었다.
